Over Ram Memory Consumption (Over 200GB)

uyelken · November 29, 2018, 07:27

Hi guys,

Im using openfoam 2.1.1 with ddtfoam solver. Also working on cluster with 240 processors. My cell number is not too much. While solver is running, ram memory consumption is increasing linearly with time. It reached over 200gb. What is the reason of that? How can i handle it?

Hi,

I was facing a similar problem and it seems like there is a bug in some openmpi versions. What version are you using?

Hi!

Did you find a solution?
I am facing a similar issue with pimpleFoam (of1806) and openMPI 3.1.3...
